A 2 lb box slides on the smooth curved ramp. If the box has a velocity of 20 ft/s at A, determine the velocity of the box when it is located at B and also find the normal force acting on the ramp at B. Assume the radius of curvature of the path at C is still 5 ft. 1) 8.8 m & 0.96
lb 

Summing up the forces
in all the directions we have: So the velocity at B is V_{B}= 8.8 ft/s At point B the summing
up all the forces acting : So the velocity of
the crate at B is V_{B}= 8.8 ft/s and
